ting mechanism or the number which com-Jv plements the said value to the next higher power yof ten appears in the other group ot setting members.

A machine ot' this class and the object of the mechanism have been fully described in the patent of the United States No. 1,075,Q?3 granted to me Januaryl 4, 1913. As shown in the said patent the coupling members are provided by gear wheels shafts which are mounted on common trame adapted to be rocked about a horizontal axis or to be shifted in the direction oi the axis oi the -gear Wheels with the gear Wheels into and out of coupling positions; For throwing the gear wheels completely out of coupling,` position the fame must perform a comparatively large rocking or shift-ing stroke7 so that it requires much room inthe machine.

The object ot the improvements is to com struct a coupling mechanism between the groups of setting members which requires less space. n, l

W ith this object in vieuT vmy invention consists in so constructing the said mechanism, that each coupling member for connecting t-Wo setting members is mounted for radial displacement ehitively to the axis of the Y settingmechanism independently of thc other coupling members, and that all the coupling members are adapted to be operated by a common operating member.

YFor the purpose of explaining the invention tivo examples embodying the same have i been shown iiilithe accompanying drawing, in Which- Figure 1, is a vvertical cross-section of a calculating machine showing the improved coupling mechanism, and Fig. 2, is a partial vertical cross-section showing a modification of the coupling mechanism.

t rEhe general construction of the calculating machine is shown and described in my .aforesaid atent No. 1,075,073, so that al detailed description sary.

1n the example shown in Fig. 1, the groups of setting members or canrdisks 1 of correspending` orders arev adapted to be coupled by means of ,gear Wheels 3 mounted on`shat'ts The said shafts 2 are disposed in radial stationary upright arms of Athe parts is not neces` slots L1 of a pair or" e. iter shitting the coupling` members opcratmg members or slides o are provided which are shit'table on 4the arms 5. The oncratinfr members 6 may be connected with or means of a push button 7 or the like from the position shown in Fig. 1 downuf'ard and in the direction ot' the arrow the coupling members are forced outward by means ot oblique slots 8 engaging the shafts 2, sothat the couplingl members are thrown out of engagement with the teeth 14 ofthe setting disks 1. By shifting the push button *I and the slides 6 in the opposite direction the coupling` members are moved in radial direction and ninto engzigement with the setting disks 1. Preferably the end posit-ions of the operating slides 6 are indicated to the operator py means of spring actuated parvis 10^engag ing* in notches 9.

In the. example shown in Fig. 2 rocking` levers 11 and 12 are provided for the coupling.;` members into and out of operatioinrvhich rocking levers are supported on arms '5'. rEhe arms 11 and 12 of the said le` vers are biurcated at their ends, and the arms l1 engage the shafts 2 ot' the coupling members 8 which are adapted to be thrown into and out of coperation \vith.the teeth 14 or the setting disks 1', and the arms 12 are adapted to be operated by means or curved operating bars 1B engaging with pins .ind the bifurcated ends of the said arms. shoivn the said bar is mounted on pins 15 engaging in slots 16 of the bar and secured to the arms 5 or, as shown, to the side walls 17 of the casing of the machine. Also in this case the arms 5 are .provided with radial slots et providing slidingsupports for the shafts 2" oi" tbe coupling members. .The slide bar 13 is adapted' to be operatedby any suitable means such for example as a push button 7, and it is adapted to be locked in` thro Wingv necting members for each pair being mounted for independent displacement toward and 10 away from the axis of the setting :mechas nisln, and common operating means for all the coupling members.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- FRANZ TRINKS.
